GUSTAV TIEDTKE, OF DORTMUND, GERMANY.

T0 aZZ whom 1' i may concern:

Be it known that I, GUSTAV TIEDTKE, a subject of the Emperor of Germany, residing at No. 16 Moltkestrasse, Dortmund, Germany, have invented certain new and useful Improvements in the Process and Apparatus for Automatically Raising ater.

of which the following is a specification.

This invention relates to an improved process and apparatus for automatically raising water, more particularly applied in cases where the head or level at which the upper water is held up is limited, andwhere a further holding up of the same cannot be ettected with the aid of the usual locking means.

In accordance with this invention the water is raised by means of basins which are closed air tight, have equal superficial areas and equal heights and are arranged directly above one another or side by side in steps with equal distances between them, and which are interconnected by water and air pipes, the water pipes opening in the bottoms, and the air pipes opening in the tops of the basins. The basins are alternately filled and discharged automatically by the air pressure by means of cocks provided in the water and air pipes and arranged to be automatically operated.

One embodiment of the present invention is illustrated by way of example in the accompanying drawings in which Figures 1 and 2 show two difiterent conditions of working, and Fig. 3 shows diagrammatically a modified form of the invention.

In the arrangement shown in Figs. 1 and 2- 1, 2 and 3 etc. are superposed basins. The lowermost basins 1 and 10 as well as the next higher basins 2 and 20 are arranged side by side for the purpose of insuring .an uninterrupted raising of water. Any suitable number of basins may be used, and the same is merely restricted by the head H (Fig. 2).

Provision must be made for permanent supply and discharge of the upper water and of the lower water, that is to say, the upper water level and the lower water level must always be maintained at the same level. The two lowermost basins 1 and 10 are therefore so arranged above the lower water or pond that their bottom is separated from the same by a distance equivalent to the height of two basins, whereasthe two next higher basins 2 and 20 are so arranged above the upper water'that their bottom is sepa- Specification of Letters Patent.

Application filed August 3, 1912.

Patented June 141,191.3 Serial No. 712,104.

From theupper water level there extends a water supply pipe 2' from which branch.

off the pipes 2' and Z, to the basins 10 and 1. The pipe 2' is then further split up into pipes i and 71 leading to the nexthigher basins 2 and 20. Further from 2' a pipe i is branched off which leads tothe basin 3 and from i a pipei, leading to the basin ll and so on. From the basins 10 and 1, the water discharges through the discharge pipes 70, and Z3, respectively into the lower water.

Likewise from the bottom of the basins 2 and 20 there extend pipes 70 70 tothe point where the raised water is to be used.

Further the basins are interconnected by air pipes. An a1r pipe f extends in an upward direction from the top of the basin 10, which. I

air pipe is provided with branches f f f which lead to the basins 20, 3, 4 and 5 respectively. Likewise the basin 1 is connected to the basin 2 by an air pipe f Air outlets 0 and c, are provided in the tops of the basins 10 and 1 which may be opened and closed. In the air pipes f 'f f etc. multi-way cocks 0 c 0, etc. are provided which allow the air topass from the top basin to the lowermost basin, and after adjustment of the respective cock, allow the outer air to flow to the basin to be emptied. Two single-way cocks may of course also be provided instead of each multi-way cock.

Further ordinary water cocks a a, a a etc.

The process of raising water in accordance with the present inventionwill now be described and at first for the purposeof the continuous raising of water to the basins 2 and 20. Y

WVhen the apparatus is not working the water cocks at, a to, 'w as well as the air cocks 0,, 0, are open, the upper water then flows uninterruptedly away to the lower water level and the head or height 00. is equal toy. To start the apparatus the basinl is filled from'the upper water or pond. For this purpose thewater cock a, is opened and the water cock to, is closed. After the completion of the filling. of the basin 1, the. air cock 0, is kept permanently closed. The

water and air cocks then assume the positions shown in Fig. 1, that is to say, cocks a a and w, and the air outlet 0, are open, while the cocks a, e @0 w are closed. The contents of the basin 1 are then discharged into the lower water or pond While the basin 2 is filled from the upper water or pond. At the same time the basin 10 is filled from the upper water, whereupon the air outlet 0 must likewise remain closed during the uninterrupted working of the apparatus. The water contained in the basin 2 may now be discharged through the drain cock w, and used for the intended purpose. The pressure of the atmosphere on the lower water maintains the water column at the level y, whereas the atmospheric pressure on the upper water maintains the water column at the level :0, so that disregarding the negligible slight difference between these pressures, and the weight of the air contained in the air pipe, equilibrium is established, that is to say 00 3 The air contained in the basin 1 which has a pressure of 1 atm. cannot be compressed either by the atmospheric pressure on the lower water or by the atmospheric pressure on the upper water.

The uninterrupted raising and discharge of water alternately to and from the basin 2 (Fig. 1) and then to and from the basin 20 is now effected by turning the water cocks a a, a and w w, 10 and 4.0 one quarter of a revolution to the right. The air cock 0, then remains permanently in the position shown in Fig. 1. If the water is to be raised farther, for instance from the basin 20 to the basin 3, then first of all the basin 10 is to be filled. For this purpose the air outlet 0 is opened, and then closed again after the filling of the basin 10. If now the water cocks o w and a and the air cock 0, are turned one quarter of a revolution to the right, and if the cook 0 is turned one quarter of a revolution to the left as shown in Fig. 2, then the contents of the basin 10 are discharged into the lower pond, and the basin 3 is filled from the basin 20. Atmospheric air is admitted through the air cook 0 to the basin 20, and the air then passes from the basin 3 through the cook 0 the pipe f and f, to the basin 10. In that case 00 is again equal to y, so that equilibrium is established. The same procedure is to be adopted in order to fill the basin 4: from the basin 3, and the basin 5 from the basin 4C, the basin 10 always being filled first, whereupon the cooks are suitably operated. Independent-1y thereof the water raising process may be continued between the basins 1 and 2. The heights of the basins may also be assumed to be less, according to the amount of upper water supplied during a unit of time, as shown in Fig. 3.

If additional basins of equal height are arranged above the upper basins in the arrangement shown in Fig. 3, then the water may be conveyed to the same automatically. For this purpose each of the basins ar' ranged above the upper basin is separately connected by an air pipe to the lowest basin,

while the upper basin is connected to the basin arranged above it, and the latter is connected with each superposed basin etc. by means of a water pipe provlded with a single-way cock. All the water pipes must as shown in Fig. 2, and since one cubic meter of water weighs 1000 kg, and one cubic meter of air weighs 1.3 kg., we get y .1000{(H+1y)1.3:atm. in kgs. per sq. m.

For superposed basins the following equation holds good:

and H must be a multiple of cl and h, where h is the height of the basin, and d the thickness of the walls of the basins.

If it is assumed that y:9 m. 11:36 In. 1:1 m.

then we get the following a 1000-[-(37.9)1.3:atm.:9036.4 kg. per sq. m.

If the air pressure only amounts to 9000 kg, then 7 must consequently be smaller than 9 m. If according to Fig. 3, (h]-(Zl is smaller than 0/2, then the water can also be raised to higher basins 3, 4-, etc. In this connection, these basins however are not to be directly superposed, but each is to be arranged separately with the distance a? be-" tween them (from the bottom edge of basin 2 to the top edge of basin 3), and further with an atmospheric pressure of only 9000 kg, the expression 00:3 must be smaller than 9 m.
